IMPROVEMENT IN MACHINES FOR TRIMMlNG AND BURNISHING THE SOLES 0F BOOTS ANDSHOEQ.

Specification forming part of Letters Patent No. 135,694., dated February 11, 1873.

To all whom it may concern:

Be it known that I, LoUIs Corn, of Saint Hyacinthe, of the Province of Quebec, of the Dominion of Canada, have invented a new and useful Improvement in Machinery for Trimming or Burnishing the Edge of a Sole or that of the I-Ieel thereof, as circumstances may require; and I do hereby declare the same to be fully described in the following specification and represented in the accompa nying drawing, of which- Figure 1 is a side elevation, and Fig. 2 a vertical and longitudinal section,of my machine. Fig. 3 is a side view, and Fig. 4. an end view, of its burnishing-sleeve. Fig. 5 is a side view, and Fig. 6 is an end view, of its cutting or rasping sleeve.

The first part of my invention relates to a separate raspingor burnishin g sleeve, a clampingguide, and an arbor, all being arranged, constructed, and combined substantially as hereinafter described, and as represented in' the drawing. The second part of the invention relates to an adjustable gage, its operative screw, and fork, arranged and combined with the rasping or burnishing sleeve, the "guide, and the arbor, all in manner and to operate essentially as specified. The third part of my invention relates to the adjustable gage provided with recesses to receive the teeth of the rasping or burnishing sleeve, in order to prevent such sleeve from revolving on and independently of the arbor so as to revolve the clamp-guide and loosen the screw thereof.

In the drawing, A denotes an arbor or shaft furnished with a pair of fast and loose pulleys, a b, and supported in boxes 0 d upheld by a suitable frame, B. The arbor projects beyond one end of the frame, and at or near its outer end is turned down to a shoulder, c, to receive upon the part f so reduced the burnishing or rasping sleeve 0, which encompasses such part f and rests at one end against the shoul der 6. The sleeve 0 is a short tube of steel, having either rasping or cutting or burnishin g teeth or projections upon its outer surface or periphery. The clamping-guide D, shown in end views in Figs. 7 and 8, in side view in Fig. 10, and in longitudinal section in Fig. 9, is inserted in and fitted to the bore of the sleeve 0 without extending quite to the adjacent end of the arbor, a clamp-screw, 9, ar-

. clamp screw.

ranged in the bore of the guide D and screwed into the arbor, serving to hold the guide, and by means of it the sleeve, to the arbor, so as to be revolved by it when it may be in revolution. This method of making the sleeve 0 and the clamping-guide D admits of the ready removal of either from the arbor for repair, or for the substitution of others of like kind as occasion may require. Furthermore, there is upon the arbor and encompassing it another. sleeve or adjustable gage, E, it being a tube moved either nearer to or further from the annular lip 11 of the clamping-guide, as the thickness of a sole to be trimmed or burnished on its edge may require, and this while the machine may be in operation.

In order to relieve the clam p-screw from any tendency to be unscrewed from the arbor by the rasping or burnishing sleeve while in revolution and pressed against a sole, the gage E is formed with recesses 0 arranged with respect to its bore, as shown in end view of it in Fig. 11. The sleeve-teeth or burnishingprojections, extending into these receivers,

will cause the sleeve to revolve with the gage and the arbor. Thus it will be seen that whichever waythe arbor may be revolved there will be no tendency of the sleeve to revolve the clampguide so as to loosen the The gage, therefore, besides performing the function of a gage, serves another purpose, as explained.

This little maehine has been found to be of great advantage or utility. By the arrangement of the gage E, the raspin g or burnishin g sleeve, and the guide together, and so as to extend on the arbor beyond one end of the frame in manner as shown, a workman can readily present to them a shoe or boot to be trimmed or burnished on its soleedge, and, while holding it, can turn it or move it as may be necessary to effect the proper reduction or burnishing of its edge, the guide-lip n being at the time inserted in the groove or space between the sole and the upper.

1 make no claim to the burnishing-machine described in the United States Patent No. 127,904, in which two or more different setting-tools are employed, one being for the shank-edge and the other being for the thicker parts of a sole.

1n my machine I make use of but one burnishing-tool with an adjustable gage. Furthermore, there is in the said patented machine no separate rasping or burnishin g sleeve and a elampingguide like the sleeve 0 and guide D as in my machine. V

By having the sleeve C separate, as de-
